Common Cause Indiana v. Lawson

The American Civil Liberties Union filed a lawsuit on behalf of Common Cause Indiana challenging an Indiana law that permits local election authorities to immediately purge the registrations of Indiana voters – without written confirmation from the voter, notice, or any waiting period – based on a match in the Interstate Voter Registration Crosscheck Program (“Crosscheck”). Crosscheck, a program administered by the Kansas Secretary of State, Kris Kobach, is inaccurate and unreliable, utilizing a matching protocol that, according to a study by a team of researchers at Stanford, Harvard, the University of Pennsylvania, and Microsoft, incorrectly flags people as potential double voters more than 99 percent of the time.
